Overview
The Milwaukee 2456-20 runs on the M12 12-volt battery platform, making it a natural complement for tradespeople already invested in Milwaukee cordless tools. At 1.55 lbs, the tool is light enough for extended use in cramped engine bays and panel spaces while offering the freedom from an air hose that pneumatic alternatives require. The 4.7-star average from 1,400 reviews reflects a broad, satisfied user base.
At $199.95, the 2456-20 is priced as a bare tool, meaning no battery or charger is included. Buyers new to the M12 ecosystem will need to factor in the cost of a battery kit, which makes the Milwaukee 2457-21 kit a useful comparison at $154.98. For those already holding M12 batteries, the 2456-20 represents a capable addition without redundant hardware.
Published specs confirm 12-volt operation and 1.55-lb weight. Torque and RPM figures are not listed for this model in the available data. Based on review volume and demand, owners across a wide range of trades report consistent satisfaction with the tool's compact footprint and cordless convenience.
Pros
- Integrates with the widely adopted Milwaukee M12 battery ecosystem
- Lightweight 1.55 lbs reduces hand fatigue during extended fastening tasks
- 4.7-star rating backed by 1,400 verified reviews demonstrates broad satisfaction

Cons
- Sold as bare tool at $199.95, requiring a separate M12 battery and charger purchase

- No monthly purchase activity listed, suggesting it may have been superseded by newer M12 ratchet models

Performance notes
The Milwaukee 2456-20 operates on 12 volts via the M12 platform and weighs 1.55 lbs. That combination positions it as a precision-oriented cordless ratchet rather than a high-torque impact wrench replacement. It suits fastening sequences where socket access is restricted and sustained air-tool noise is undesirable. Power source is cordless; a compatible M12 battery is required and not included.
What buyers say
Owners across the 1,400-review pool consistently appreciate the M12 platform compatibility, noting seamless battery sharing with drills and drivers. The compact size and cordless convenience draw the most positive mentions. Criticisms tend to focus on the bare-tool pricing for a product that requires a separate battery investment, and some buyers flag the absence of published torque specs.
